[PATCH v2 0/5] rockchip-dsi for rk3568

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

This series adds support for the dsi and dphy controllers on the
Rockchip RK3568. I can confirm that for the Rockchip RK3568 this
current series DOES WORK now, but it requires rolling back clk changes
made for the HDMI driver. If the clock changes are not rolled back, the
image on the screen is shifted about 100 pixels to the right.

Clk changes in question:

Tested on an Anbernic RG503 and RG353P with clock changes rolled back,
the hardware works correctly on both devices.

Changes since RFCv1:
 - Identified cause of image shift (clock changes).
 - Noted that driver works now.
 - Added devicetree nodes for rk356x.dtsi.
